 Title    Investigations of Solid Polyborates and their Aqueous Solutions by Raman Spectroscopy  
 Abstract    Raman spectra of solid H3B03, Na2[B405(0H)4] • 8 H20, K[B506(0H)4] • 2 H20 and Na[B(OH)4] were recorded between 300 and 1500 cm -1 as well as of borax in aqueous solutions as a function of concentration and pH. Because of better solubility in water, the Raman spectrum of ammonium tetraborate in aqueous solution was also recorded as a function of pH. For comparisons the Raman spectra of solid (NH4)2[B40s(0H)4] • 2 H20, /S-NH4[B506(0H)4] • 2 HsO, NH4[B506(0H)4] • 0,67 H20 and NH4[B506(0H)4] were con-sidered. In solution, all lines in the Raman spectra could be assigned and the degree of depolarization measured. The assigned Raman frequencies can be used for the identifica-tion of unknown B-0-lines and therefore of unknown borate or polyborate structures.
